Description
Technical field
The utility model is related to a kind of noise reduction tail-gate push rods.
Background technology
Electric tail gate is mainly used in high-grade car and SUV, the main electric opening for realizing luggage case or boot, electricity
It is dynamic to close (remote control switch or the control of tail-gate switch)；Simultaneously in order to adapt to various operating modes in use, it is also equipped with anti-pinch,
Barrier overcomes, and soft stop is stopped, the basic functions such as self-defined open angle.
Electric tail gate push rod includes inner tube, outer tube, and a casing is fixedly installed in outer tube, and sleeve upper end is solid with outer tube
Fixed, lower end fixing nut is arranged rotatable lead screw in inner tube, and lead screw upper end passes through nut as in casing, on lead screw
End connection block is for preventing lead screw upper end from being screwed out from nut.
Existing this structure there are the problem of：It is difficult to realize between lead screw and casing concentric, that is, lead screw upper end is in casing
When middle mobile, there is showing for block scratch internal surface of sleeve pipe due to decentraction between lead screw and casing in the block of lead screw upper end
As causing push rod that noise occurs in operation.
Utility model content
The technical problems to be solved in the utility model is：Overcome the deficiencies of the prior art and provide a kind of noise reduction tail-gate push rod.
Technical solution adopted by the utility model to solve its technical problems is：A kind of noise reduction tail-gate push rod, including inner tube
And outer tube, rotatable lead screw is set in said inner tube, is fixedly installed casing in the outer tube, it is solid in the nozzle of described sleeve pipe lower end
Surely it is provided with nut, the lead screw upper end passes through nut as in casing, and the lead screw upper end forms mounting post, the mounting post
On be fixedly installed roll wheel assembly；
The roll wheel assembly includes turning rolls, and the turning rolls includes interior mounting ring, outer mounting ring and more intermediolateral columns,
Each intermediolateral column both ends are fixedly connected with interior mounting ring and outer mounting ring respectively, the interior mounting ring and the fixed setting of outer mounting ring
In mounting post, be respectively sleeved on several rotatable idler wheels on each intermediolateral column, described sleeve pipe inner wall and each idler wheel it
Between there are mobile spaces.
Further, lead screw mounting post outer end forms riveting end, and the riveting end is by turning rolls axial compression
In mounting post.
Further, the intermediolateral column quantity between the interior mounting ring and outer mounting ring is 6.
Further, the idler wheel is made of nylon material.
The utility model has the beneficial effects that：A kind of noise reduction tail-gate push rod is provided, the idler wheel being arranged in lead screw upper end is passed through
Component forms when non-concentric between lead screw upper end and casing, between internal surface of sleeve pipe and idler wheel and rolls cooperation, avoids previous lead screw
It is scratched between internal surface of sleeve pipe because contacting firmly.
Roll wheel assembly is made of the turning rolls of tubular, and multiple trundles are arranged on each intermediolateral column, contact is made to get up more
It is sensitive, even small contact also directly can drive trundle to rotate, effectively reduce noise.
Description of the drawings
The utility model is further illustrated below in conjunction with the accompanying drawings.
Fig. 1 is the utility model push rod schematic diagram；
Fig. 2 is lead screw schematic diagram；
Fig. 3 is distribution map of the intermediolateral column in interior mounting ring；
Wherein, 1, inner tube, 2, outer tube, 3, lead screw, 4, nut, 5, roll wheel assembly, 51, interior mounting ring, 52, outer mounting ring,
53, idler wheel, 6, casing.
Specific implementation mode
The utility model is further described presently in connection with attached drawing.These attached drawings are simplified schematic diagram only to show
Meaning mode illustrates the basic structure of the utility model, therefore it only shows composition related with the utility model.
As shown in Figure 1 to Figure 3, rotatable silk is arranged in inner tube 1 in a kind of noise reduction tail-gate push rod, including inner tube 1 and outer tube 2
Bar 3 is fixedly installed casing 6 in outer tube 2, and nut 4 is fixedly installed in 6 lower end nozzle of casing, and 3 upper end of lead screw passes through nut 4
As in casing 6,3 upper end of lead screw forms mounting post, and roll wheel assembly 5 is fixedly installed in mounting post.
Roll wheel assembly 5 includes turning rolls, and turning rolls includes interior mounting ring 51, outer mounting ring 52 and 6 intermediolateral columns, 6
Intermediolateral column both ends are fixedly connected with interior mounting ring 51 and outer mounting ring 52 respectively, and interior mounting ring 51 and outer mounting ring 52 are fixedly installed
In mounting post, be respectively sleeved on several rotatable idler wheels 53 on each intermediolateral column, 6 inner wall of casing and each idler wheel 53 it
Between there are mobile spaces.
3 mounting post outer end of lead screw forms riveting end, and riveting end is by turning rolls axial compression in mounting post.
